【摘要】：为解决渠道流量在线实时监测问题,依据声学多普勒频移的物理原理,开发了底座式IQ渠道流量自动监测系统,实现了流量数据实时自动采集,并通过GPRS等信道传送到中心站。中心站可对数据进行分析、处理、存储、转录、发布以及远程实时查询流量、工作状态、时段水量等。以云南牛栏江-滇池补水工程输水线路末端站为例,介绍了系统的工作原理、安装测量过程,分析了其监测精度。结果表明,与美国SONTEK公司的M9走航式声学多普勒水流剖面仪相比,IQ系统的测量误差在±5%以内,最大误差为-6.71%,系统误差为-0.9%,满足相关规范要求。
[Abstract]:In order to solve the problem of on-line real-time monitoring of channel flow, based on the physical principle of acoustic Doppler frequency shift, a pedestal IQ channel flow automatic monitoring system is developed. The real-time and automatic collection of flow data is realized and transmitted to the central station through channels such as GPRS. The central station can analyze, process, store, transcribe, publish and remotely query the traffic, working status, period water and so on. Taking the end station of the water conveyance line of Niulanjiang-Dianchi Lake supplementary water project in Yunnan as an example, this paper introduces the working principle of the system, the process of installation and measurement, and analyzes its monitoring accuracy. The results show that the measurement error of the IQ system is within 卤5%, the maximum error is -6.71 and the systematic error is -0.9, compared with the M _ 9 acoustic Doppler flow profiler of SONTEK Company, which meets the requirements of relevant specifications.
